본 고안은 섹터기어에 핀치로울러를 착설하여 이 섹터기어가 로오딩모우터에 의해 구동되어 핀치로울러를 압착 시켜주도록한 비디오 테이프 레코오더(VTR)의 핀치로울러 압착장치에 관한 것이다.The present invention relates to a pinch roller pressing device of a video tape recorder (VTR) in which a pinch roller is installed on a sector gear so that the sector gear is driven by a loading motor to compress the pinch roller.
종래의 브이티알은 핀치로울러를 압착시켜주기 위한 구조가 복잡하여 많은 부품과 공수가 필요하게 되었고, 또 이런점에 의해 소형화하는데 큰 어려움이 있었다.The conventional VTIAL has a complicated structure for compressing the pinch roller, which requires a lot of parts and a lot of labor, and also has a great difficulty in miniaturization.
본 고안은 이와같은 점들을 해결하기 위해 로오딩 모우터의 구동력을 로오딩기어에 전달하여주는 각 기어들중 하나에 치합시킨 섹터기어에 핀치로울러를 착설하여 이 섹터기어가 핀치로울러를 압착시켜주도록 하므로 핀치로울러의 압착장치의 구성이 매우 간단하게 되도록 고안한 것으로 첨부 도면에 의거 상술하면 다음과 같다.In order to solve these problems, the present invention installs a pinch roller on a sector gear that is fitted to one of the gears that transmits the driving force of the loading motor to the gear, so that the sector gear can compress the pinch roller. Therefore, the configuration of the crimping device of the pinch roller is designed to be very simple.
로오딩모우터(1)의 구동력을 기어(2)(2')(2")(2''')에 의해 로오딩기어(3)(3')로 전달하여 써플라이로오딩아암(4) 및 테이크업 로오딩아암(5)을 동작시켜주어 테이프(6)를 헤드드럼(7)으로 로오딩시켜주도록한 것에 있어서 기어(2")에 섹터기어(8)를 치합시키고, 이 섹터기어(8)에는 핀치로울러(9)를 선단에 축착한 아암(10)의 중간을 주축(11)으로 회동되게 축착하여 후단부가 스토퍼핀(12)에 걸리도록 하며, 이 아암(10)은, 비틀림스프링(13)을 선단에 핀치로울러(9)를 축착하는 스크류(14)와 스토퍼핀(12)사이에 걸어서 탄력설치되게 하여서된 것이다.The driving force of the rowing motor 1 is transmitted to the rowing gears 3 and 3 'by the gears 2, 2', 2 "and 2 '' 'so that the supply arm 4 And operating the take-up loading arm 5 so that the tape 6 is loaded into the head drum 7 by engaging the sector gear 8 with the gear 2 " 8) the pinch roller 9 is pivotally pivoted to the main shaft 11 by pivoting the middle of the arm 10, which is affixed to the tip, so that the rear end is caught by the stopper pin 12, and the arm 10 is a torsion spring. (13) is to be elastically installed by walking between the stopper pin (12) and the screw (14) for pinching the roller (9) to the tip.
미설명 부호 "15"는 캡스턴축이고, "16"은 테이프 가이드 핀이며, "17"은 텐션 아암이고, "18"은 텐션폴이며, "19. 19' "는 경사핀이다.Reference numeral "15" is a capstan shaft, "16" is a tape guide pin, "17" is a tension arm, "18" is a tension pole, and "19.19 '" is an inclined pin.
이와같이 된 본 고안의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention made as follows.
로오딩모우터(1)가 구동되면 각 기어(2)(2')(2")(2''')가 회전되어 구동력을 로오딩기어(3)(3')에 전달하여 써플라이로오딩아암(4)과 테이크업 로오딩암(5)이 테이프(6)를 헤드드럼(7)으로 통상의 방법대로 로오딩시켜주게 되는데, 이러한 과정에서 기어(2")에 의해 섹터기어(8)도 동시에 회전된다.When the rowing motor 1 is driven, each gear 2, 2 ', 2 ", 2' '' is rotated to transmit driving force to the rowing gears 3, 3 'to supply The arm 4 and the take-up loading arm 5 load the tape 6 into the head drum 7 in the usual manner. In this process, the sector gear 8 is also driven by the gear 2 ". Rotates at the same time.
이때 섹터기어(8)는 "A"위치에서 "B"위치까지만 회전이 되고, 또 섹터기어(8)가 이들 간격만큼 회전이 되면 테이프(6)는 로오딩이 완료된 상태이므로 로오딩모우터(1)는 작동이 정지되는 것이다.At this time, the sector gear 8 is rotated only from the "A" position to the "B" position, and if the sector gear 8 is rotated by these intervals, the tape (6) has been loaded because the loading motor ( 1) is to stop operation.
이렇게 하여 섹터기어(8)가 회전이 되면 이 섹터기어(8)에 축착된 아암(10)도 동시에 제1도 가상선(a)에서 보는 바와같이 이동되어 그 선단에 축착된 핀치로울러(9)가 캡스턴축(15)에 압착이 되며, 이때 비틀림스프링(13)이 약간 압축되기 때문에 압축되는 만큼 핀치로울러(9)를 캠스턴축(15)에 압착시켜주게 되는 것이다.In this way, when the sector gear 8 is rotated, the arm 10, which is stuck to the sector gear 8, is simultaneously moved as shown in the first virtual line a, and the pinch roller 9 is stuck to the tip thereof. Is compressed to the capstan shaft 15, and the torsion spring 13 is slightly compressed so that the pinch roller 9 is compressed to the camston shaft 15 as much as it is compressed.
이와같이 작동하여 테이프의 로오딩 작동과 핀치로울러를 압착시켜주게 되는 본 고안은 언로오딩시에는 로오딩모우터가 역구동되어 로오딩시와는 반대의 동작이 진행되어 모든 부품이 초기의 상태로 되돌아가게 되어 언로오딩이 되는 것으로 로오딩 모우터의 구동력을 전달하는 기어에 핀치로울러를 착설한 아암을 스프링으로 탄력설치되게 축착한 섹터기어를 설치하여 핀치로울러를 압착시켜주도록 하였기 때문에 그 구조가 매우 간단하여 부품 및 공수가 대폭 감소되며, 또 이런점에 의해 기기를 소형화하는 데도 매우 적합한 고안이다.In this way, the rolling operation of the tape and the pinch roller are compressed so that the rolling motor is reversely driven during unloading, and the reverse operation of the loading is progressed, and all the parts are returned to their initial state. The structure is very simple because the pinch roller is pressed into the gear that transmits the driving force of the low motor by installing a pinch roller elastically installed by spring. Therefore, the number of parts and labor is greatly reduced, and this is a very suitable design for miniaturizing the device.
